The image of the Vanity Fair cover featuring her debut has been retweeted more than 230,000 times and favorited more than 260,000 times. By comparison, the Glamour cover featuring Kim Kardashian's pregnancy announcement (also released yesterday) only got 3,000 Twitter mentions. That's a fairly stark contrast.

And in a head-to-head battle, it looks like Caitlyn can take home the gold, big time. Her #CallMeCaitlyn hashtag has been used nearly 232,000 times on Twitter as of around noon today, according to social media analytics firm Brandwatch. Meanwhile, Kardashian's #BreakTheInternet hashtag received 171,000 mentions over three days, according to Brandwatch.
